Flash 如何从actionscript发出同步URL请求？

我在actionscript中有一个大循环，它将大量数据发送到url：

for(var i=0;i<1000;i++) {
    var request:URLRequest = new URLRequest();
    request.url = url;
    request.method = URLRequestMethod.POST;
    request.data = data;

    var loader:URLLoader = new URLLoader();

    loader.load(request);
}

---

for（var i=0；i您不能进行同步调用，但您可以等到服务器应答后再发送另一个请求

但是，如果你真的必须在一个循环中向一个Web服务器发送一千个请求，那么可能存在设计缺陷

// small example to see how do the chaining call

class A extends EventDispatcher {
 private var urlLoader:URLLoader;
 private var urlRequest:URLRequest;
 private var sendCount:int=0;

 //......

 public function init(url:String):void{
  urlLoader=new URLLoader();
  urlLoader.addEventListener(Event.COMPLETE, sendData);
  urlRequest = new URLRequest();
  request.url = url;
  request.method = URLRequestMethod.POST;
  count=1000;
 }

 //....
 private var data:Object;

 //.....
 // 
 function sendData(e:Event=null):void{
  if (count-- > 0) {
   urlRequest.data = data; // put the data based on the counter
   urlLoader.load(urlRequest);
  } else {
   urlLoader.removeEventListener(Event.COMPLETE, sendData);
   dispatchEvent(new Event(Event.COMPLETE));
  }
 }
}


var a:A=new A();
a.addEventListener(Event.COMPLETE, function():void{
 trace("send finished");
}); // listen to the event complete so
    // you know when you send is finished

a.init("http://...."); // ok init your send
a.sendData(); // and start the send that will be chain each time the webserver answer
